GUSTAF N. NELSON, OF DENVER, COLORADO.

WEED-FULLER.

To all whom it may concern:

Be it known that I, GUsTAF N. NELSON, a citizen of the United States,residing in the city and county of Denver and State of Colorado, haveinvented certain new and useful Improvements in lVeed-Pullers; and I dodeclare the following to be a full, clear, and exact description of theinvention,'such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

My invention relates to improvements in weed pullers, my object being toprovide a device adapted for use in pulling or uprooting noxious weedsas dandelions in lawns or other locations where the extermination ofweeds is desirable or necessary.

My improved device consists of a pair of members pivotally connectednear their upper extremities and having a toggle joint connection neartheir lower extremities which are formed into weed pulling jaws.

The connection of the two members is such to cause the two jaws tomalntam a parallel or. approxnnately parallel position throughout theirlength when closed thus giving a considerable weed grasping surfacewhereby a firm hold of the root may be obtained. A rod connects onemember of the toggle with a handle pivotally attached to one of the mainmembers. This handle is spring-actuated whereby the two jaws are heldnormally in the open position.

Having briefly outlined my improved construction, I will proceed todescribe the same in detail reference being made to the accompanyingdrawing in which is illustrated an embodiment thereof.

I11 this drawing, Figure 1 is a side elevation of my improved deviceshowing the jaws in the closed position. Fig. 2 is a similar Viewshowing the jaws in the open position. Fig. 3 is a section taken on theline 3 3 F 1g. 2 vlewed 1n the direction of the arrow. Fig. 4 is asection taken on the line 4r 1 Fig. 2 looking in the direction of thearrow.

The same reference characters indicate the same parts in all the views.

Let the numerals 5 and 6 designate the two main members of the device.ber 5 is provided with a handle part 7 extending approximately at rightangles to the Specification of Letters Patent.

body of the member. The member 6 is pr0- vided at its upper extremitywith a short arm 8 which is pivotally connected with the member 5 asshown at 9. The lower extremity of the member 5 is provided with a flatjaw 10 cooperating with a similar jaw 12 forming a part of the member 6.The members 5 and 6 are further connected just above the jaws 10 and 12by a link 13 and a bell crank lever 14. The link is pivotally connectedwith the member 5 as shown at 15 and with an arm 16 of the bell cranklever as shown at 17. The lever 14 is fulcrumed on the member 6 as shownat 18 while its arm 19 is pivotally connected as shown at 20 with a rod21 whose opposite extremity is movably connected as shown at 22 with anoperating handle member 23 pivoted on the member 5 as shown at 2 1. Thishandle member 23 is connected by means of a spring 25, with a lug 26formed 011 the member 6. Normally the spring maintains the members inthe position shown in Fig. 2 of the drawing whereby the jaws 10 and 12are open or separated to their limit of movement. The degree or width towhich the aws may open is controlled by an adjusting screw 27 which isthreaded through the handle member 23 and normally engages the upperextremity of the member 6.

The members 5 and 6 are preferably T- shaped in cross section (see Fig.3) while the handle members 7 and 23 are curved or rounded, the one uponits upper surface and the other upon its lower surface as shown at A, Brespectively (see Fig.

From the foregoing description the use and operation of my improveddevice will be readily understood. Assuming that the operator desires topull a weed, the jawslO and 12 when in their open position are insertedin the ground whereby the jaws are on opposite sides of the root or weedto be removed. The jaws are then'closed on the root by the operator whopresses the handle member 23 toward the member 7, thus causing the jawsto close by virtue of the connection between the handle member 23, thebell crank lever 14 and the link 1321s heretofore described. Theinstrument is then drawn upwardly carrying the weed or plant with it aswill be readily understood. It is evident that by adjusting the screw 27whereby its lower extremity shall protrude, a longer or shorter distancethrough the handle member 28, the width to which the jaws main membersand the other pivotally conare allowed to open may be readilycontrolled.

Having thus described my invention, what I claim is:

l. A weed puller comprising two main members having cooperating jaws attheir lower extremities and pivotally connected above the jaws, twohandle members, one being rigid with one of the main members, while theother is pivotally connected therewith, a rod connected with the pivotedhandle member, and an operative connection between the rod and the twomain members at a point between the jaws and the pivotal connection ofthe said members, whereby as the pivoted handle member is actuated, thejaws of the two handle members are caused to close, substantially asdescribed.

2. In a device of the class described, the combination of two mainmembers having jaws at their lower extremities and pivotally connectedtogether above the jaws, two cooperating handle members, one beingrigid'lzy connected with a main member and the other pivotally connectedtherewith, and an operative connection between the pivoted handle memberand the two main members at a point between the jaws and the pivotalconnection of the two main members, substantially as described.

3. The combination of two main members having cooperating jaws at theirlower extremities, the said members beingpivotally connected togetherabove the aws, two handle members, one being rigid with one of thenected therewith, a rod attached at one extremity to the pivoted handlemember, a link and lever connection between the two main members at apoint below the pivotal connection of the two members, the lever beingconnected with the opposite extremity of the said rod, substantially asdescribed.

i. A device of the class described, comprising two main members havingjaws at their lower extremities and pivotally connected above said jaws,two handle members, one rigidly connected with one main member, and theother pivotally connected therewith, a suitable connection between thepivoted handle member and the two main members below their pivotalconnection, and a spring connecting the pivotal handle member with oneof the main members and normally acting to hold the jaws in the openposition, substantially as described.

A device of the class described, comprising two main members having jawsat their lower extremities and pivotally connected above said jaws, anoperating handle member pivotally connected with one of the mainmembers, and an operative connection between the pivoted handle memberand the two main members below the pivotal connecti on of the latterwhereby as the handle member is actuated the main members are operated,substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
